Suitable for underwater robots, swimming pools; underwater ranging
L04-module is an ultrasonic underwater obstacle avoidance sensor designed based on underwater applications. It has the advantages of small size, small blind spot (minimum 2cm), high precision and good waterproof performance.
Replace traditional cameras and meet the requirements of underwater obstacle avoidance at normal sailing speed. Underwater vehicles use obstacle avoidance sensors, which can be truly "unmanned"; without human eye observation, underwater vehicles can be controlled at will.

Precautions
(1) The response time measured at 9600 BAUD rate; (2) The module is stationary at 30CM underwater, the water temperature is 25℃, the water surface is calm, and there is no water flow. The data obtained from the test, S represents the current distance; (3) The module is stationary at 30CM underwater, the water temperature is 25℃, the water surface is calm, and there is no water flow. The data obtained from the test using PVC pipe at 0.7 meters
